Hello guys I need your help, I own a 2007 FLHXI and I was cruiing in PA doing some stop and go's and all ove a sudden the motor seem to almost quit it was running on one cylinder. I swapped the plugs becasue the looked real fouls and had a brown shiny coating which tells me it was overheated, nothing still the same then I swapped the wires and started it up again,, still the same (Missing) so I went for the coil and crossed my fingers and started it still the same . WHAT COULD IT BE, I NEED YOUR HELP GUYS!!!!

check the plug on the rear injector...

 

My 07 Road King Classic did that. I too thought it was the coil and replaced the coil. It turns out it was the ECM. had to replace the ECM.

 

check compression, I had a 07 ultra stick the valve in the guide causing low compression. Mike

 

Where is the ECM located on the Street Glide if I may ask, and also I appreciate the quick comeback. I will try to locate it.

Thanks again
Harley Dave

 

The ECM on my '09 is right under the seat.

 

i have an 07 flhxi and had the same problem about 2 weeks ago. motor was not holding fuel pressure. there is a plastic tube in the tank that looks like a flexi-straw. over time that tube can crack and mess up fuel pressure. same symptoms as what you were describing. worth checking out. good luck.

 

checked all the hoses and they were fine i want to thank you all for the assist, will keep you posted. The ECM wouldn't be on the side compartment on the right side by the seat?

Thx
HD Dave

 

do you have a power commander/ fuel pac added to the bike? if so try to disconnect it and see if the bike runs on both cylinders

 

HD Charlie will that kind of eliminate the PCI if it starts on both cylinders?
